A noob problem, I was trying to follow a finger rigging tutorial vid when I ran into a transform puzzle. It’s a simple three bones rig on Y axis with bones’ Z axes point up. The starting and ending points of the bones are perfectly aligned with Y axis.
I was trying to rotate all three bones with Y axis constraint in Edit Mode, so the bones’ Z axes are pointing downward. But it doesn’t do anything even though Tool panel shows it has been rotated. Rotating it in X and Z constraint works fine. The workaround is to switch to Object Mode, then I can rotate it 180 degree with Y axis constraint. So what am I missing here? Thanks in advance.
Thank you, motimo. Numerical input in the Object’s Transform parameter rotates the bone, Ctrl-R rolls it too but rotation in Transform remains unchanged. Both do the job, which is change bone’s orientation. What is the difference between Roll and Rotate in Edit Mode?
There is no rotation for bones in edit mode. There is only a location for the head, a location for the tail, and the roll. The rotation you highlighted in the screen shot is for the armature object, not the bone. You can rotate bones in edit mode, but it just changes the location of the head and tail. AND rotating on the Y axis of the bone doesn’t set it’s roll. Maybe it should, but it doesn’t.
